Stability and Reactivity of Enzymatic Papers

Nov 9, 2009

Mohidus Samad Khan

Bioactive papers and paper diagnostics are getting a reality for their low cost, selectivity and application flexibility. Critical is the thermal stability of bioactive papers that need to be shipped and stored. This study quantifies the thermal stability and reactivity of enzymatic bioactive...

Computational Fluid Dynamics Simulation of a Quadupole Magnetic Sorter Flow Channel

Nov 9, 2009

V. S. K. Sajja

Isolation of the pancreatic islets is the important step in preparing islets for the transplantation in type 1 diabetes patients. Quadrupole magnetic flow sorting (QMS), effective in the separation of suspensions of single cells, is being modified for isolation of pancreatic islets. The separating...

A National Technology and Business Transformation Roadmap for Smart Process Manufacturing

Nov 9, 2009

Jimmy Humphrey

Session highlights and fundamentals of smart manufacturing plants will be presented.

DNA Biosensors for the Detection of Hippuricase Gene of Campylobacter Jejuni Based SPREETA and dotLab Platforms

Nov 9, 2009

Tony Gnanaprakasa

DNA-biosensors allow rapid, real-time monitoring of hybridization with the target nucleic acids. These biosensors are gaining more attention over traditional diagnostic methods for their fast and responsive operation, and their cost effective design. Specificity of the system relies on...

Experimental Investigation of Mixing Time in a Stirred, Torispherical-Bottomed Tank Equipped with a Retreat-Blade Impeller

Nov 9, 2009

Nonjaros Chomcharn

Glass-lined reactors are typically used in the pharmaceutical and specialty chemicals industries because of their material compatibility with most reactants and their cleanability. These reactors are typically equipped with a retreat-blade impeller placed close to the bottom of the tank a single...

Rapid Surface Enhanced Raman Scattering (SERS) Viral Assays

Nov 9, 2009

Patrick A. Johnson

Rapid and accurate detection is the key to controlling the spread of viral pathogens. Recent advances in the field of surface enhanced Raman scattering (SERS) spectroscopy have demonstrated the utility of this technology in diverse research disciplines ranging from surface chemistry and...

Commercial-Scale Energy Crop Production: Establishing Switchgrass in Tennessee

Nov 9, 2009

Timothy Rials

With the advancement of cellulosic ethanol technologies in recent years, more emphasis is being placed on the production of a sustainable supply of biomass for commercial scale facilities. These facilities will require significant supplies of biomass that will, in the southeast, come from private...

Designing Sustainable Options for Bioenergy Crops

Nov 9, 2009

Virginia Dale

Currently, the complexity and scale dependency of land-use decisions and their impacts are not understood, defined, or described with adequate clarity to enable policy makers to develop strategies to ensure a sustainable bioenergy future with acceptable environmental and socioeconomic consequences...

Enzymatic Bioprocessing of Cellulose in N-Methyl Morpholine Oxide/Water

Nov 9, 2009

John Collier

To enzymatically convert biomass to biorefinery feedstock, biofuels, or hydrogen an environmentally friendly solvent or process is needed to disrupt the microstructure of lignocellulosics. In multi-stage processes, solvents are being used as pretreatments by dissolving cellulose and precipitation...

Aerobic Fermenter Scale-up: Why Equal Mass Transfer Scale-up Doesn't Always Work

Nov 9, 2009

Julian B. Fasano

Transferring oxygen to the liquid is only one of several steps that must occur in an aerobic fermentation. After the oxygen is transferred to the liquid, the liquid must be thoroughly mixed throughout the vessel. Then the oxygen must diffuse through the cell wall before finally being metabolized...
